Generally, law is a set of rules that governs the behavior of people in society. These rules may be enforceable by governmental institutions. Law also shapes history and economics, and plays a major role in politics and society.

There are several types of legal systems. These include common law, civil law, religious, and customary law. Each has its own features, but all share certain similarities.

Common law legal systems are characterized by an explicit acknowledgement that decisions made by the courts are “law.” In addition, they feature a number of doctrines, including precedent and analogy.

Civil law legal systems involve less detailed judicial decisions. In addition, they involve a systematic body of equity that developed alongside rigid common law. The system uses the concept of precedent, which means that decisions made by higher courts bind lower courts to a particular decision.

The concept of “natural law” emerged in ancient Greek philosophy, and was re-entered into mainstream culture through the writings of Thomas Aquinas. In modern times, it has become important in both domestic and international legal systems.

Civil law systems are primarily composed of legislative statutes and judicial decisions. They are typically shorter and less detailed than common law legal systems.

Legal reasoning involves using logic and reasoning to find the answer to a particular legal question. In contrast, legal interpretation involves using linguistic and systemic interpretation to derive the answer to a legal question.

Legal issues can occur for a variety of reasons. They can be due to unexpected events, planned events, or problems at work or in the family.
